Every homeowner should consider replacing their home's windows at some point. If you haven't replaced your windows lately, you may be missing some signs that you might need to do so. Here are a few signs that it's time to consider having your home's windows replaced:

Your Windows are Really Old

No windows are expected to exceed a lifespan of 40 years, but many types of windows aren't expected to last longer than 8 years or so. The expected lifespan of your windows depends on their type. Here's the average lifespan of various window types:

• Aluminum: 15 to 20 years.

• Double Pane: 8 to 20 years.

• Wood: 30 years.

• Vinyl: 20 to 40 years.

• Skylights: 10 to 20 years.

If the expected lifespan of your windows has passed, schedule an inspection with your service provider so they can help you decide whether it's in your best interest to replace the windows now.

You Can't Stop the Air Flow

If you're experiencing unwanted airflow through your windows, you should try sealing them to block the drafts. Just apply caulking or spray foam insulation around the windows between the panes and frames both inside and out. After the insulation product you chose to use dries, you can sand the frames and repaint them.

If you're still experiencing drafts after the windows have been sealed, the windows are probably too worn to provide your home with the protection it needs from the outdoor elements. In this case, your best bet of eliminating those unwanted drafts is to replace your windows altogether.

You Can No Longer Ignore the Damage

Another good reason to consider having your home's windows replaced is if they're damaged. Whether cracks, chips, or scratches have developed, the damage could get worse over time and make your windows more vulnerable to severe damage overall. If a tree branch hits a damaged window, it could shatter and damage items in your home.

Worse yet, it could injure a loved one who happens to be near the window at the time. So avoid all the dangers of living with damaged windows and have any windows that are cracked, chipped, or scarred in any other way replaced as soon as possible. You'll be rewarded with added safety and comfort in the end.
